Abstract: 116,747. Edison Accumulators, Ltd., Monnot, J. F., and Lewis, E. W. June 15, 1917. C o n t r o l lers, actuating- mechanism f o r; sliders.- The rectilinearly moving member of a controller is moved step by step in either direction through springs at each end strained by an operating-rod which carries a detent normally in engagement with a toothed rack. Contacts b are fixed over insulating - material f such as micanite supported by steel plates e on the frame a. The fixed contacts d consist of carbon brushes mounted in holders g and held against the moving contacts by the hooked ends of spring- controlled rods h. A rack l with two sets of oppositelyinclined teeth is secured to the casing and is engaged in a step-by-step manner by the double-ended detent m pivoted on the end of a lever m<1> which is in turn pivoted on the frame a and is held down by the spring m<11>. An arm m<3> of the detent enters a slot in the cuntroi rod o which can slide through the frame a. Sprinbs r, s are mounted within a sleeve q on the rod o, the spring s serving as a buffer. When the rod o is operated, the spring r is compressed and one end of the slotted portion of the rod o engages the detent arm m<3> to release one of the detent ends from the rack. The spring then moves the frame a forward to the extent of one tooth when the detent again engages the rack.

Title: Self engaging couplings
Inventor: BIRKENSHAW DERIC
IPC: G21C13/067
Filed: 1960-03-11
Abstract: 952,328. Stud and socket fastenings. NUCLEAR POWER PLANT CO. Ltd. March 9, 1961 [March 11, 1960], No. 8724/60. Heading E2B. [Also in Division G6] A self-engaging coupling for locking a sealing plug to a standpipe 4 in a nuclear reactor comprises a cage 1 inserted in the upper end of the standpipe 4 with its end face 1c abutting a sealing face 4b in the standpipe, sealing rings 6a being located between these faces 1c, 4b. The sealing plug (not shown) is secured to the lower end of a cylindrical member 5 slidable within the cage 1, the extent to which it can so slide being limited by a stop formed by a ledge 1a on the cage abutting a ledge 5a on the cylindrical member. To prevent gas leakage between the sliding surfaces of cage 1 and member 5, sealing rings 6 are provided. A number of balls 2 are housed within apertures in the cage wall and during an initial condition when the coolant gas pressure acting on the coupling is substantially removed, four of the balls 2 (spaced 90 degrees apart) are displaced into recesses 3 in the standpipe 4 by means of forks 7 located in holes 8a in a lifting head 8. The remainder of the balls 2 are displaced into corresponding recesses 3 when the gas pressure on the coupling is restored since this results in upward movement of the member 5. The resultant force acting on the balls 2 is transmitted to faces 4a on the standpipe and face 1b of the cage, exerting a force on the latter in the opposite direction to the resultant force A due to the gas pressure. This urges end face 1c of the cage into sealing contact with face 4b on the standpipe. The lower end of member 5 which supports the sealing plug does not need to form a seal with the standpipe wall and therefore the seal is independent of differential expansion between the coupling and the standpipe. The coupling cannot be released until the resultant force due to the gas pressure is removed when the member 5 drops under its own weight until it is held by the ledge 1a of the cage 1. Specification 894,471 is referred to.

Abstract: 952,454. Regulating; reciprocating pumps, centrifugal pumps. C. E. MASON. June 2, 1961 [March 14, 1960], No. 8856/60. Headings F1A, F1B and F1C. [Also in Division F2] In fire engine pumping apparatus, one control 10 Fig. 1 controls engine speed and a second control 11 engages or disengages through a clutch a reciprocatary pump-priming device (not shown) a spring-loaded locking member 12 moves transversely of the paths of movement of the controls and a cam element 13 is operatively arranged between the member and one of the controls so that the pump priming device cannot be engaged above a predetermined engine speed nor can the engine speed be increased beyond the predetermined speed when the pump priming device is engaged. Movement of control 10 to increase speed causes cam 13 to engage ball-end 12A and moves the rod member 12 to the left, against spring 16, to prevent movement of the lever 11. If lever 11 is in the engaged position the movement leftwards of rod member 12 is prevented and ball-end 12A engages the cam to prevent engine speed increase. In a modification the cam element 13 may alternatively be fixed to the end of rod member 12. In another embodiment, when lever 10 Fig. 6 is moved past the engine-speed-regulating position, cam 34 displaces rod member 25 into the path of movement of fin 23 so that the primer pump control bar 21 cannot be moved to engage the primer device. If the control bar 21 is in the engaged position, the fin 23 obstructs movement of rod member 25 which prevents movement of lever 10 past the predetermined position. Movement of bar 21 engages and rocks the lever 40 of a normally shut spring- loaded valve 41 which is thus opened to connect the priming device with the pump chamber.

Title: Manufacture of carboxylic acids of the hydroaromatic series
IPC: C07J75/00
Filed: 1937-03-30
Abstract: Carboxylic acids of the hydroaromatic series are prepared by the oxidation of ketones of the general formula R-CO-CH3 where R stands for a cyclopentanopolyhydrophenanthrene nucleus with a hypohalogenous acid.  The preferred oxidizing agent is iodine in the presence of an alkali.  Nuclear double bonds are preferably protected by halogen during the oxidation.  In an example acetoxypregnenolone is allowed to stand 24 hours at room temperature in alcoholic solution with caustic soda and iodine. The reaction product is poured into water and extracted with ether to give an acid of the formula <PICT:0493055/IV/1> which may be de-acetylated by boiling with dilute mineral acid.  A sample has been furnished under Sect. 2 (5) of the aetio-cholanic acid produced by the oxidation of 3-acetoxy pregnanolone in methanol solution with iodine and potassium hydroxide.  The Specification as open to inspection under Sect. 91 comprises also a general statement that compounds of the character of the sex hormones are obtained by the oxidation of compounds of the general formula R-CO-CH3 where R stands for a cyclopentanopolyhydrophenanthrene residue.  Two additional examples are included in which acetoxypregnenolone is oxidized by means of iodine in methanol solution to give 3-acetoxy-aetio-cholenic acid, the conditions under which the oxidation takes place being slightly varied.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in helicopters
IPC: B64C27/16
Filed: 1927-04-04
Abstract: 289,248. Bleecker, M. B. April 4, 1927. Screw and like propellers.- A lifting-screw for a helicopter comprises main aerofoils 26 pivoted about tubular shafts 21 radiating from a central column 20, auxiliary aerofoils S being carried by the main aerofoils and acted upon by the airflow to control the angle of incidence of each main aerofoil separately in order automatically to maintain its lift constant throughout the cycle. Manual means are provided for displacing the line of thrust of the screw independently of the automatic action by causing cylindrical adjustments of the auxiliary aerofoils. Means also are provided for acting upon all of the auxiliary aerofoils simultaneously to vary the pitch of the screw. A variable and reversible pitch screw for steering purposes also is described. The shafts 21 are stayed to the column 20 by rods 28 passing through slots in the aerofoil surfaces. The screw is driven round by propellers P on shafts 32. driven by motors on the blades or from a shaft 34 extending through the column 20. Each auxiliary aerofoil S, which may be at the front or rear of the main aerofoil, is pivoted about a shaft carried by trusses 42 from the main aerofoil, and an arm 45 on each aerofoil S is connected by a rod 46 to a normally vertical arm 43, Fig. 11, projecting through a slot in the main areofoil surface. The centre of gravity of this structure is not coincident with the pivotal axis of the aerofoil 26 and the lengths of the arms 45, 43 are so chosen as to make the desired correction. The arms 43 are connected to shafts 47 carried in bearings in the shafts 21 and extending outwardly therefrom, and the inner ends of these rods are cranked and connected by rods 65 to a. ring 52, Fig. 6, which rotates about a ball 51 on a sleeve 50 surrounding the shaft 34. A non-rotating ring 54 surrounds the ring 52 and is connected by rods 59, 64 to two frames 56, 60 pivoted to the sleeve 50 about axes at right angles to one another. The frame 60 is tilted by a connection 69 to a lever 67 which is pivoted to a shaft 68 which moves the frame 56 through a link 71. Lateral and longitudinal movements of the lever 67 thus effect a tilting of the ring 52 in any direction to effect a displacement of the thrust of the lifting-screw. The sleeve 50 is raised and lowered to vary the pitch of the screw by connections to a lever 76 at the pilot's seat. The variable pitch propeller for steering comprises a hollow hub 83, Fig. 12, through which passes a, movable rod 85 connected by links 90 to arms 89 on the blades V which are normally at neutral incidence. The rod 85 is moved by a bell crank lever 99 coupled to the rudder actuating gear.

Abstract: 102,585. Igranic Electric Co., (Cutler- Hammer Manufacturing Co.). June 30, 1916. Driving machines.-Means responsive to the load on a working motor are employed to control a feed-motor to regulate the supply of work to the main motor. The winding of the vibrating relay S is connected in series with the working motor A, and the relay, when lifted, short-circuits a resistance R in the shunt field circuit of the feed-motor B. If the load on the working motor A increases above a predetermined limit, the relay will respond and the field of the motor B will be strengthened. The feed of work to the motor A is therefore diminished. The arrangement may be applied to alternating-current motors. The windings of the relay S<2>, Fig. 4, are connected in the stator circuit of the working motor A. The resistance R<2> in the rotor circuit of the feed motor B<1> is normally short-circuited by an electro-magnetic switch M<1>.
